Sub-Zero 4204490 Refrigerator Water Filter Replacement Cartridge 2 Pack

They are filters that are normally changed every 6 months, depending on the use you give to this equipment, the filters that are used in freezers are changed approximately every year or more, even so the same Sub-Zero equipment counts the amount of use through the amount of water that passes through these filters, which is why it is a very good and reliable product, at least for me, I have checked the water that comes out through them countless times, and they really do a very good job, Excellent !

Does the job

Works as intended.

Used in our subzero fridge and freezer - thank you

A bit pricey but at least it’s available, unlike at the subzero factory store.

I purchased these and I thought it was installed correctly and was working until I needed to change out. Noticed it was not being used to filter water. I contacted Sub-Zero and told me that they are probably counterfeit ones and I received one of there's and compared them. That ends were slightly different but there's worked just fine and turned like it should. It was past the 30 days to send back. I would not purchase filters for a Sub-Zero other then Sub-Zero directly. Never know what you will get here. Now I an out money and filters. Thanks

Filter was a direct replacement. No issues or leaks.

It's hard to really rate this since I have not inserted the filter in to the refrigerator system yet....waiting for the message that I need to do this, but.....I am prepared!

Sub-Zero 4204490After a stint with third party filter ... I went back to these.1. Ice tastes better ... Which leads me to believe if those third party filters actually do anything.2. No fear of leaks from the seal of the filter... Third party sometimes leaks and it was a real pain.3. I bought a 25000$ fridge and skimping on a filter ... Doesn't make sense.Stick with this. Can't go wrong.

Works exactly as expected
